Electrical Panel Upgrades in Seattle & Shoreline, WA
Upgrade aging 100-amp panels and service entrances to modern 200-amp systems.
If your panel is full, your breakers keep tripping, or you're adding a heat pump, EV charger, or addition, it's time for a service upgrade. We replace outdated 100-amp and fuse-based panels with modern 200-amp, 40-space breaker panels and bring the service entrance, grounding, and meter base up to current code at the same time.
Many Puget Sound homes still run on panels from the 1960s–80s — some with brands or designs that inspectors and insurers flag. We install Square D QO professional-grade panels and breakers because they're reliable, widely available, and easy for any future electrician to service. A new panel also means proper GFCI and AFCI protection on the circuits that need it.
We coordinate with your utility (Seattle City Light, PSE, or Snohomish PUD depending on your area) for the service drop or lateral, pull the permit, and schedule the inspection. You're left with a labeled, balanced, safe panel and room to grow.

Panel and Service Upgrades — Your Questions Answered
How do I know if I need a panel upgrade or just more circuits?
If your panel still has open spaces, adding circuits may be enough. If the panel is full, you're tripping breakers, your service is under 200 amps, or you're adding large loads like an EV charger or heat pump, a service upgrade is usually the right call. We'll assess it on site.
How long does a panel upgrade take and will I lose power?
Most residential service upgrades are completed in a single day. Power is off for a few hours while we swap the panel and meter base; we'll tell you the exact window so you can plan around it.
Do I need a permit for a panel or service upgrade?
Yes — electrical service upgrades require a permit and inspection in Washington. We pull the permit through your local jurisdiction and schedule the rough and final inspections so the work is code-compliant and signed off.
Which panel brand do you install?
We install Square D QO professional-grade panels and breakers — reliable, widely available, and easy for any future electrician to service. We use 200-amp, 40-space panels as a standard residential upgrade.
Can you upgrade my panel for an EV charger or heat pump?
Yes. If your current service can't carry the new load, we upgrade to 200 amps (or add a subpanel) and run the dedicated circuit for the charger or heat pump at the same time.
Will you coordinate with my utility — Seattle City Light, PSE, or Snohomish PUD?
Yes. We confirm which utility serves your address and coordinate the service drop or lateral, meter base, and inspection with the right provider.

"I had an incredible experience getting service done from All City Electric. I wanted to have some outlets fixed as well as install a Level 2 Charger. They were easy to schedule a time for an estimate and also for the service. The electrician came right on time for both appointments and was very respectful and sweet. Every team member was very kind and sweet and accommodating. I would highly recommend them for any future service needs you have!"

"I called All City Electric when my laundry room and living room lights would not turn off. If you tried to turn them off they flicker. Then 5 of my outlets either didn't work or things would fall out of them. I finally got sick of it and reached out explaining my situation. The gal that answered my call was very sweet and kind. Even when I called back the next day saying I forgot to write it down and wanted to confirm my appointment day and time. We had a good laugh. She made my day! Today, Kevin showed up on time and confirmed the problem and got to work right away. He was pleasant and kind during the entire process. He answered all my questions. Thank you to the entire staff and owner of All City Electric!! You will forever have my business. Please call if you have any issues. They are absolutely the best to work with!! Thank you again!!"
